Mate Connector

robert_scott_jr_

In a project I have a spring that is meant to be part of a handle. In the part studios I have assigned a mate connector to the center of the spring and I have assigned a mate connector a point in the handle where I want the spring to be located in the Assembly. In the Assembly, the mate connector of the spring is no longer located in the position I assigned it to in the part studio. This misplacement does not allow me to position the spring along the handle. What have I done wrong? Is there a better method to accomplish this assembly of those two parts? - Scotty

Found a solution but cannot tell you why it works or if it helps in your ultimate assembly model design.

Another thought. If you want to mate the spring with the handle it would be much easier to do so in the same part studio (just create both the handle and spring in one studio and transform/mate there) OR do all the final mating in the assembly but not in the handle studio using a derived part from another part studio.

This can probably be pulled off by those who have a very deep understanding of OS and ALL of its nuances but for me it just means trouble, or least a post looking for answers on this forum.

Thanks for your response and solution. After attaining the desired result following your advice and then continuing on I noticed that I had two spring connectors; One in the assembly and one in the part studio. Evidently I did attempt to join the handle and spring in the part studio. Perhaps assigning two like connectors to the same part and then attempting to join both to one other part was the source of the problem rather than the transforms. I agree that the part studio would be the better place to do it, reasoning that they are essentially one part and perhaps avoiding some complication/clutter in the assembly (at least for this novice). - Scotty

Yeah I created both the spring and the handle in the same part studio, assigned mates and connected them there. Worked as expected but I think there's no reason not to create all the parts in their own part studio and mate them in the assembly. Avoids confusion and keep the assembly as the mating medium, perhaps as intended.

Scotty, I have a quick question for you. I was going to duplicate the spring you have but saw that the part was derived and linked from another document so I couldn't see how it was done. Could you share how you got that conical shape from what I assume is a helix and a sweep?

Thanks

Thanks I figured it out, if anyone wants to know how let me know.

Thank you Scotty - appreciate you taking the time. Looks like that same way I got it done - eventually
